First, I'm a bit sorry for my somewhat sarcastic tone earlier. You're also right about some things.
That said, your research basically differs from what the Korean Political Science Association states. Regardless, both of Korea's two major political parties fundamentally like authority and censorship. Looking at their actual censorship policies, both have done quite similar things. So what difference is there? Mainly, Korea's conservative party-affiliated newspapers have more influence, so they are stronger at agenda-setting.
Judging by your tone, I think you basically understand Korea through the lens of Christian conservative issues, especially related to religion. But in reality, there are complex circumstances behind it.
First, as you said, the issue of 'fake news' is fairly complicated in Korea. Starting with the Yoon Seok-youl administration imposing heavy penalties on actual 'real news' by labeling it as fake news through the KCSC, there has been basic political pressure on algorithmic intervention by Korea's major platforms. Also, President Park Geun-hye conducted KakaoTalk surveillance and a blacklist of the cultural sector. But these insider details don't get conveyed to you as a foreigner. Why is that?
It's partly because Korea's left-leaning news media lack global competitiveness. Your perspective is mostly colored by Korean Christian conservatism. Why might that be? Probably because your news about Korea mostly comes through Korean-American Christian conservative media outlets. And Christian groups in Korea are closely connected to the far right. Why? Because religious groups can easily provide personnel to help with election campaigning, so there is a collusive relationship. Anyway, I don't think your perspective is entirely wrong, but your tone was so intense and you so harshly 'condemned' the opposing side that I became a bit sarcastic. Your perspective does make some sense.
However, I do think there is a problem with the materials available for foreigners to study this issue. That also feels like part of Korea's lack of global competitiveness
Ah there's the "You are foreigner you will never understand" line!
You went from Democratic Party is akshually conservative to "everybody censors in korea, you dont get us" but if both sides censor, then my point stands: the Democratic Party does not get laundered as harmless just because it uses words that sound nice and formal.
I'm not a christian and it really doesn't change the previous actions to ban anti-North Korean activists sending leaflets, lawfares against journalists and non bipartisan arbitration of the press.
Earlier you said that AI censorship is okay because the whole country benefits economically from more AI use and that it should be exported to other countries. Now you are blaming Christians.
I don't think you are coming across as rational or persuasive and the constant condescending tone towards foreigners in general is off putting. I think if anything you are unable to recognize your own political bias and trying to gatekeep Korea as this weird orientalist object. and it really isn't.
